There is nothing about the ntpq output that couldn't be trivially
faked by a malicious server operator. Mode 6/7 capability adds no true
security or assurance to the users of an ntp server. Authentication
does not solve this problem either.

In reality, all public ntp servers are "black boxes", because you
can't trust anything they tell you, including the time. This is why
you configure a diverse set of time servers.
